It's probably the same HAL name length issue from the "Probotix PBX
cape on BBB can't start linuxCNC" thread.

Can you try the fix from:

I've pushed an update for the example BeagleBone configurations, but
for anyone who has this issue, the simple sed 1-liner fix for your HAL
file is (quoted to avoid line wrap):

> sed -i '/\[PRUCONF\](DRIVER) /s/$/ halname=hpg/;s/\[PRUCONF\](DRIVER)\./hpg./;/addf hpg/s/ servo/ servo/' YourConfig.hal

Thanks Charles

But i already made those changes to hpg and halname=hpg awhile ago

the only lines that refer to hal_pru_generic  are the first couple lines

thanks gary

Well, then what's in your /var/log/linuxcnc.log file?

I did a clean install of the machinekit i think dated 05/17/2015 to test received the same error msg.
then did an update upgrade and now can load linuxcnc at all am getting this error now

 MACHINEKIT - 0.1
 Error in startup script: couldn't load file "/usr/lib/tcltk/linuxcnc/bxcnc.so": librtapi_math.so: cannot open shared object file: No such fictory
     while executing

     invoked from within
 "source [file join [file dirname [info script]] .. linuxcnc.tcl]"
     (file "/usr/lib/tcltk/linuxcnc/bin/pickconfig.tcl" line 29)

also attached a copy of the error files

yes, reading the log definitely helps:

"Apr 27 00:08:48 bbb msgd:0: hal_lib:3164:rt hal_pin_newfv:28 HAL error: length 49 invalid for name starting 'hal_pru_generic.stepgen.00.dbg_pos_minus_'

how more detailed can the error message possibly be than "length invalid" ? I do not know what else we possibly could do.

It is all there in front of you - but you need to look at it.

i did see it but i am not a programer and i am not sure what to change seeing i already went thought this before
the name to long and changed all the hal_pru_generic to hpg its been OK till now..

I started over and did a fresh install of MK dated 2015/05/25

I tried to run linuxcnc for first time loaded and picked my system beaglebone bebopr++ lineardelta  then aborted error on the first run the ini file was the default no modes made to it..

still think its the long file name problem, but not sure I made all the changes to the hal file that Charles instructed me to do when I received that error a while back and all has been fine till recent updates

put 4 error files on pastebin not sure yet how you want me to link you to them or do you want a zip of then. any way here's

is a link  http://pastebin.com/u/gorf24

That's still the HAL name is too long error:

hal_pin_newfv:28 HAL error: length 49 invalid for name starting
'hal_pru_generic.stepgen.00.dbg_pos_minus_'

I recently checked in fixes for this which should have made it to the
packages by now, but you'll need to manually update:

sudo apt-get update
sudo apt-get upgrade

...since it will be a while before this fix makes it to the pre-built
images. To check to see if you're using the new version, look for a
halname= parameter on the loadrt line for the PRU driver in your HAL file.

i tried the manual update after updating i cant load linuxcnc aborts right away with this error msg

MACHINEKIT - 0.1
Error in startup script: couldn't load file "/usr/lib/tcltk/linuxcnc/bin/../lin$
    while executing
"load [file join [file dirname [info script]] linuxcnc[info sharedlibextension]$

    (file "/usr/lib/tcltk/linuxcnc/bin/../linuxcnc.tcl" line 60)
    invoked from within
"source [file join [file dirname [info script]] .. linuxcnc.tcl]"
    (file "/usr/lib/tcltk/linuxcnc/bin/pickconfig.tcl" line 29)

seems the upgrade is messing other stuff up..

thanks gary

Hi

If your last error is anything to go by, the report you get has no
relationship to the actual cause, it
is just what falls over next after the error

Run echo "" > /var/log/linuxcnc.log to zero it

start machinekit afresh to load the same config
(we need to know what the config is too and if it is not a stock sample
config, attach it)

then attach your linuxcnc.log to a post

Previously you had errors which appeared to evolve around tcl, but were
in fact still because you had a
huge long pin name originating from hal_pru_generic being loaded under
that name instead of hpg

viz *"Apr 27 00:08:48 bbb msgd:0: hal_lib:3164:rt hal_pin_newfv:28 HAL

error: length 49 invalid for name starting

'hal_pru_generic.stepgen.00.dbg_pos_minus_'*

the ini file that i get from a fresh install and an update, upgrade doesn't have and reference to the halname= or hpg
I have made the changes to the hal file for the hpg and halname=hpg

but after the update upgrade is when i can't boot lenuxcnc at all

attached a fresh copy of the log file and my ini and hal

thanks gary

You replaced one too many hal_pru_generic instances with hpg. The one
on the loadrt line needs to *STAY* hal_pru_generic (or something that
expands to that, like the "[PRUCONF](DRIVER)" in most of the example
configs) since that's _still_ the name of the actual driver:

Apr 20 05:41:23 beaglebone msgd:0: rtapi_app:3861:user hpg: dlopen:
hpg.so: cannot open shared object file: No such file or directory

your correct sorry must have missed that hal_gerenic_ i fix it  and reran lenuxcnc also cleared out the linuxcnc log file

this is the error i received when trying to load linuxcnc don't think it loaded very far, it also never written anything to the linuxcnc.log file that was blank empty

this is the terminal error echo message
